1.  Water:

  • Ensure availability and sustainable use of water and sanitation for Bishops.

4.1 Bishops will be entirely self-reliant on all its water sources through borehole (underground) water, rainwater or any externally collected storm water runoff that comes onto campus.
4.2 Bishops will reduce water consumption through ecological design (using water-wise plants) and through other innovative green technologies.
4.3 Bishops will recycle and reuse all other forms of waste water – storm and grey - on campus through ecological design (e.g. reed bed filtration systems), increasing reservoir capacity, improving recycled water quality for drinking and using other innovative green technologies to reduce water consumption and reuse water.
4.4 All toilet systems on Bishops campus will be waterless thereby establishing a complete reduction in any previously produced black water.
4.5 Bishops to become self-reliant for its non-potable water needs.
4.6 Introduce waterless urinals in all areas of the school.
4.7 All major renovations and retrofits need to have low water usage.
4.8 Must use ecological design and/or other technologies to improve water efficiency (e.g. high-efficiency faucet aerators, high-efficiency pre-rinse spray valves, energy star qualified dishwashers, FOG tanks).
4.9 All watering of sports fields must be computerised to improve efficiency.
4.10 Grounds on campus that don’t need water must be identified and further water must be stopped completely or seasonally.
4.11 Where possible grassed areas to be replaced with water-wise plantings or Astro Turf.
4.12 Installing a second reservoir for recycling and reuse purposes.
4.13 Rainwater harvesting to be implemented and used within houses.
4.14 Timer systems to be installed in all house showers, appropriately limiting shower length and access to hot water.
4.15 Install water-monitoring system to establish water usage.
4.16 Retrofitting water-saving devices in all buildings on Bishops (e.g. low flow showerheads).
4.17 Install pool covers for both pools.
4.18 Fix all leaking faucets.
4.19 Using biodegradable cleaning materials.
4.20 Install waterless hand sanitiser in all bathrooms.
4.21 Conduct visual surveys on all water usage on campus (e.g. leaking tap audit).
4.22 Review method of reporting water leaks and wastage and, if necessary, implement improved method for all boys and staff on campuses.
4.23 Immediate strategies to reduce water consumption in all parts of the school (e.g. timed showers on campus, water flower beds only in morning and evening).
4.24 Only the playing fields and common school grounds are allowed to apply for special exemption from normal residential restrictions applicable at the time.
4.25 Increased use of on-site reservoir by purifying water for reuse.

What has been done in 2017?

4.15 In discussion with Terra Firma on this matter. Borehole measuring, monitoring and management is being discussed and set up.
4.16 Retrofitting is being carried out as best as possible
4.17 To be confirmed.
4.18 Ongoing issue, re-looking into reporting of water issues system, in an attempt to set up something more immediate and appropriate.
4.19 Using biodegradable cleaning materials is now standard practice.
4.20 Waterless hand sanitiser has been established in all bathrooms.
4.21 A visual survey has been done on water and tap leakages. Discussion is being had around the reporting of this to Maintenance.
4.22 See 4.21.
4.23 With the introduction of Level 4 water restrictions, Bishops is making every attempt to move off municipal water supply and put in strategies around water saving.
A huge step that Bishops made was to introduce a different uniform policy during the drought which meant that boys could wear sports clothing to lessons, instead of changing clothes and thereby creating more washing.
Discussions are being had around how Bishops can move off municipal water completely and sustainably use and manage its ground water resources.
Permeable paving and underground storage tanks have already been set in place (under hockey astro parking lot), looking to recycle storm water where possible but this is ongoing process that needs to be integrated into the future planning and spatial understanding of the Bishops campus.
New main pipes are going to replace the asbestos pipes, which will reduce the water wasted at Bishops through leaking.
Ground water sterilisation through chlorination is being set in place to ensure the safety of our drinking water.
4.24 Only non-potable water is being used to water grounds and playing fields. These are also being watered at times when evaporation rates are low. Water wise irrigation methods are being implemented and being used for watering.
4.25 A larger project is being investigated on the storage, sterilisation and utilisation of groundwater on campus. A holistic, integrated watering system is being considered in an attempt to reduce water consumption as well as implement new technologies and equipment to ensure Bishops’ water future.
Other There has been huge awareness at Bishops at all levels regarding water during this 2017 drought season and this is something that will be ongoing.
